PAD FOR INDELIBLE MARKING.

SPECIFICATION forming part of Letters Patent No. 411,264, dated September 17, 1889.

Application filed June 24, 1889. Serial No. 315,302. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH R. SMITH, of WVaterbury, in the county of New Haven and State of Connecticut, have invented a new Improvement in Pads for Indelible Marking; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side View of the disk complete, looking toward the division of the ring; Fig. 2, a top View; Fig 3, a vertical section of the disk; Fig. 4., the ring detached; Fig. 5, a vertical section illustrating the operation of the pad.

This invention relates to a device for holding fabrics for indelible marking.

Heretofore these pads have been produced in the form of a round wooden disk with a ring of slightly-largerinternal diameter, and so that fabric placed over the wooden disk and the ring set over the fabric and disk would draw the fabric close upon the surface of the disk. It is to this class of pads that the invention particularly relates. In this previous construction of pad the ring is inelastic, and varying thicknesses of fabric vary the clam ping capacity of the ring.

The object of my invention is a simple c011- struction of pad in which the clamping-ring may be adapted to various thicknesses of fabric and hold all with equal strength; and the invention consists in a metal disk having a downwardly-proj ecting rim with an outwardly-proj ecting flange from the edge of the rim to form a shoulder, the disk presentinga flat surface combined with a divided elastic metal ring the internal diameter of which is no greater than the diameter of the disk, and so that said ring may be placed over the disk, and in so doing expand according to the thickness of the material which may be placed over the disk and clamp that material firmly around the edge of the disk, and as more fully hereinafter described.

A represents the disk, which is made from metal, presenting a smooth surface, and is of substantially circular shape. Around its edge is a downwardly-projecting rim a, terminatin gin an outwardly-proj ecting flange b, which forms a shoulder around the disk.

B represents the ring. This is made preferably from round elastic wire, as steel, and of a diameter preferably slightly less than the diameter of the disk, and is divided as at (Z to permit the expansion and contraction of the ring.

The fabric to be marked is placed over the disk, as seen in Fig. 5, then the ring set over the fabric around the disk and-pressed down upon the rim (1., coming to a rest upon the flange or shoulder b, the ring yielding according to the thickness of the fabric. In this pressing of the ring over the fabric and disk it draws the fabric tight over the disk, and leaves it smooth and firm and easy to write upon. The metal presents a very smooth surface upon' which to write, and the ring adapts the pad for use for a great variation in the thickness of fabric.

From the foregoing it will be understood that I do not claim, broadly, a pad for indelible marking composed of a disk and clamping-ring; but

\Vhat I do claim is A metal disk of substantially circular shape having a downwardly-proj ectin rim a around its edge, the said' rim terminating in an outwardly-proj ectin g flange Z), forming a shoulder around the disk, combined with an elastic divided metal ring B, adapted to be set around the disk and yield to varying thicknesses of fabric which may be placed upon the disk, substantially as described.

JOSEPH R. SMITH.
